History
In 1883 Gaston Tissandier was the first to use electric motors in airship propulsion. The following year, Charles Renard and Arthur Krebs flew La France with a more powerful motor.
Nikola Tesla envisaged using electrically powered aircraft, powered by beams from the ground or the ionosphere.
Electric motors have been used for model fixed-wing aircraft since from at least 1957, with a challenged claim from 1909.
In 1964 William C. Brown demonstrates on CBS News with Walter Cronkite a model helicopter that receives all of the power needed for flight from a microwave beam.
In 1973, Fred Militky and Heino Brditschka converted an HB-3 to an electric aircraft. Heino flew it for 14 minutes that same year.
In 2007 the non-profit CAFE Foundation held the first Electric Aircraft Symposium in San Francisco.
In 2009, a team from the Turin Polytechnic University made a conversion of a Pioneer Alpi 300. It flew 250 km/h for 14 minutes.
By 2011 the use of electric power for aircraft was gaining momentum. At AirVenture in that year the Electric Aircraft World Symposium was held and attracted wide attention. It was sponsored by GE Aviation and included presentations by US Air Force, NASA, Sikorsky Aircraft, Argonne National Labs and the US Federal Aviation Administration.

Famous quotes containing the word history:
“The disadvantage of men not knowing the past is that they do not know the present. History is a hill or high point of vantage, from which alone men see the town in which they live or the age in which they are living.”
—Gilbert Keith Chesterton (1874–1936)
“Bias, point of view, fury—are they ... so dangerous and must they be ironed out of history, the hills flattened and the contours leveled? The professors talk ... about passion and point of view in history as a Calvinist talks about sin in the bedroom.”
—Catherine Drinker Bowen (1897–1973)
“The second day of July 1776, will be the most memorable epoch in the history of America. I am apt to believe that it will be celebrated by succeeding generations as the great anniversary festival. It ought to be commemorated, as the day of deliverance, by solemn acts of devotion to God Almighty. It ought to be solemnized with pomp and parade, with shows, games, sports, guns, bells, bonfires and illuminations, from one end of this continent to the other, from this time forward forever more”
—John Adams (1735–1826)
